CNC waterjet machines are complex systems that combine high-pressure water cutting technology with computer numerical control (CNC) for precision cutting. Here are the main mechanical components of a CNC waterjet machine:

1. High-Pressure Pump:
   • Converts regular water into a high-pressure stream (up to 60,000 psi or more).
   • Can be either direct drive pumps or intensifier pumps.
2. Cutting Head:
   • Includes a nozzle, mixing chamber, and abrasive delivery system (for abrasive waterjets).
   • The water stream exits through a jewel orifice, and abrasive particles are added in the mixing chamber.
3. Abrasive Hopper and Delivery System:
   • Stores and delivers abrasive material (e.g., garnet) to the cutting head.
   • Ensures a steady flow of abrasive to the mixing chamber.
4. X-Y-Z Gantry System:
   • Provides the movement in the X, Y, and Z axes to position the cutting head.
   • Typically driven by servo motors and precision ball screws or linear motors for high accuracy.
5. CNC Controller:
   • The brain of the machine, it controls the movements of the gantry system.
   • Processes the cutting paths generated from CAD/CAM software.
6. Work Table:
   • The surface where the material to be cut is placed.
   • Often includes a grid or slats to support the material while allowing water and debris to pass through.
7. Water Catcher/Tank:
   • Located beneath the work table to collect the used water and debris.
   • Can have features like water level controls and debris removal systems.
8. Filtration and Recycling System:
   • Filters the used water and removes debris.
   • Some systems allow for water recycling to reduce consumption.
9. Safety Enclosures and Shields:
   • Protect the operator from the high-pressure stream and flying debris.
   • Include doors, windows, and interlocks.
10. Cooling System:
    • Maintains the temperature of the high-pressure pump and other components.
    • Essential for long-term operation and to prevent overheating.
11. Software Interface:
    • Allows the operator to program and control the machine.
    • Includes features for designing parts, generating cutting paths, and monitoring machine status.

These components work together to ensure the precise and efficient operation of a CNC waterjet machine, making it a versatile tool for cutting a wide range of materials.
